SPECIFCATON forming part of Letters Patent No. 666,211, dated January 15, 1901.

Application filed November 16, 1900. Serial No. 36,736. (No model.)

To all wiz/m, t may ccm/067%: designed to pass after being severed from the Be it known that I, HOWARD G.

Said disk has a plurality of aperformly divided by being passed through the tures D, through which the chips of Wood are disintegrating-pins, are blown by the current generated by the rapid rotation of the wings C to a conveyer to-be carried Wherever desired. Y

From the foregoing it will bea-observed that by arranging the various parts as shown and described I embody in a single machine the chip-cutting mechanism, the disintegratingdisk, and means for pneumatically conveying the uniformly-divided chips of wood without the necessity of providing a separate machine for cutting the chips, crushing the same, and the use of a fan for conveying the material to the conveyer or other mechanism to be carried to any desired place.

Having thus described my invention, what A I claim to' be new,and desire to secure by Letcomprising a disk mounted on a suitable shaf.t aA casing surrounding said disk, knives. carried by the disk, against which the log of wood is fed, a rotary and a stationary disk each carrying disintesratins-pins mounted Within said casing, and means for pneumat-l ically conveying theuniformiy-reduced chips of Wood from the casing, as set forth,

3. A combined Wood. chipper and crusher, comprising a rotary disk and shaft carrying the same, a casing surrounding said disk, an aperture in said casing, knives carried by the disk, against which a log of wood is fed,

through said aperture in the casing, a rotary and a stationary disk carrying disintegratingpins, which intermesh with one another, and

means within the casing for creating a pneumatic current for conveyingthe uniformlyreduced chips of Wood therefrom, as set forth.

4. An apparatus for chipping Wood and crushing the same, the combination with the casing, an aperture therein, Va rotary shaft mounted in said casing, a disk having apertures and carrying a series of cutting-knives mounted over apertures therein, and against which logs of wood are fed, and a series of wings about the circumference of -said disk, for creating a pneumatic current, whereby, the chips of wood are blown from the casing, las set forth.

5. A combined Wood chipper and crusher, vcomprising a casing, a shaft rotating therein, an aperture in said casing, a flanged disk having apertures and rotating With said shaft and havingV a series of laterallyprojected Wings about its circumference, and cuttingknives'- mounted over the apertures in the face of said disk, against which a log of wood .is fed at an angle, a trough th rough` which the `log of Wood is fed, a, disk K fastened to the lwinged disk, disintegrating-pins carried by :said disk K and a stationary disk secured to the casing, disintegrating-pins carried by said .stationary disk, which pins intermesh with the pins on' the disk K, as set forth,

6. In combination with the winged disk, a A1disk K secured thereto, pins having flanged 4heads which are countersnnk in said disk K, having their heads flush. with the outer face of said pin-carrying disk K, and held in place by the inner face of the Winged disk, as shown `and described.

In testimony whereof I aiiiX my signature lin presence of two witnesses.
